Hello.
For the NV2 default priority I suggest you guys @ MikroTik add the Counter-Strike game protocol and the like.
Of course these as well: tcp syn on port 80, 443, UDP DNS, tcp ack with small size, DSCP EF, and others.
Regards.
P.S. everyone ! suggest more! Thanks.
P.S. 2 note that priority is ABSOLUTE while the priority queue is transmitting, the other one is waiting. So be careful what you add here.
